2 Claims. (Cl.-16091) This invention relates to a wind screen for attachnien'tto the windows of a cab of a locomotive and has for'its 'primary' object to protect the operator from the elements and at the same time provide clear vision both forward, to the side, and to the rear of the cab.

Another object is the provision of an attachment which may be folded into compact space when not in use and leaves the window opening entirely unobstructed.

Among its features my invention embodies a pair of spaced frames carrying transparent panels and having guide channelsin which a flexible member of transparent material is slidably mounted to enclose the window opening to afford protection to the operator.

In the drawings:

Figure 1 is a horizontal sectional view through the wall of the cab of a locomotive showing my improved attachment in place, certain portions of the device being broken away to more clearly illustrate the details of construction,

Figure 2 is'a side view of Figure 1,

Figure 3 is a vertical sectional view taken on the line 3-3 of Figure 1, and

Figure 4 is a detailed sectional view taken on the line 4-4 of Figure 3.

Referring to the drawings in detail, a wall l forming one of the side walls of the cab of a locomotive is provided with a window opening I I which is adapted .to be inclosed by my improved wind screen designated generally l2.

The wind screen I2 comprises a rectangular frame l3 of a size substantially equal to that of the window opening ll. Hinged as at M to the vertical side rails of the frame I3 is a pair of screen frames designated generally l5 each of which comprises a vertical channel [6 the upper and lower ends of which are joined by an arcuate channel I! and fitted in the channels l6 and I1 is a panel l8 of transparent material such as glass. Welded or otherwise secured to the bight portion of the channel I! and following the armate contour thereof is a guide channel [9 the opened side of which is perpendicular to that of the channel I1.

As will be noted in Figure 3, the channels I! and I9 terminate at points substantially tangential to the horizontal and arranged in alignment with the upper ends of the channels I 9 on the 50 inside of the window opening H are horizontally extending guide channels 20 which are held in place to the cab wall In by means of suitable brackets 2|. The forward ends of these guide channels align with the upper ends of the chanthrough the sides.

, STATES PATENT OFFICE nels l9 and slidably arranged in the guide channelsl9 and 20 is a panel 22 of a suitable flexible transparent material such as'is commonly found on the general market. It will be noted that the upper ends of the channels l3 and the outer ends of the channels 20 are slightly below the upper wall of the window opening H so as to allow the flexible panel 22 to freely slide therethrough.

In operation when it is desired to use the device to protect an engineer or other operator of the locomotive from the elements the frames l5 are swung outwardly on their hinges M to a position perpendicular with the side of the cab wall Ill, as illustrated in Figures 1 to 3 inclusive. In this position the guide channel-s l9 align with the guide channel 20 and the flexible panel 22 may then be pulled from the guide channels 22 into the channels l9 and downwardly following the curvature of the channels to the bottom of the frame l3 so as to afford a complete enclosure for the 'window opening ll. Due to the transparency of the panels l8 and of the flexible member 22 it will be obvious that clear vision may be had both to the front and rear of the locomotive as well as Thus the engineer may lean out of the window opening II and yet be completely protected from the elements.

When it is desired to have the window opening ll completely open the flexible panel 22 may be elevated to slide horizontally in the channels 20 which it is to be understood will be made long enough to support the full length of the flexible member. If so desired suitable reinforcing strips 23 may be embedded at spaced intervals in the flexible member 22 to prevent it sagging when supported horizontally between the channels 20. Having disposed of the flexible member in a horizontal position between the channels 22 the frames 15 may be swung on their hinges l4 into the dotted line position illustrated at Figure 1 which results-a clear unobstructed window opening ll.

Should it be found desirable a windshield wiper of conventional construction may be attached to the vertical bar It of each frame Hi to operate over the transparent panel l8 supported therein. .While in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details of construction, combination, and arrangement of parts may be resorted to without departing from the spirit and scope of the invention as claimed,

What I claim is: 1. The combination with the side wall of the operator of the locomotive from the elements when he is occupying the normal driving position in the locomotive cab.

tical side bar of the first mentioned frame and extending outwardly from the outer side therefore, a transparent panel in each frame, and a flexible member of transparent material carried between the frames and adapted to form a convex housing to protect the operator of the locomotive from the elements when he is occupying the normal driving position in the locomotive cab, and-horizontally extending members at and perpendicular to. the upper end of the window 7 opening between which the flexible transparent 2. The combination with the side wall of the o, .7

cab of a locomotive having a window opening therein, of a wind screen for inclosing said open-1 ing without obstructing" clear vision therethrough which comprises a frame adapted to be attached tothe outer face of the Wall of the cab adjacent theiwindow opening, a frame hinged to each vermember is adapted to be supported when the window is to be wholly open.
